How much meat can we eat — sustainably?

Scientists find that a small amount of animal products could have a place in our diets without wreaking environmental havoc. But it’s far less than what we consume today, and only if farmed in just the right way.

How sustainable are fake meats?

Marketed to meat lovers, plant-based burgers like Impossible and Beyond claim to taste like the real thing and to have far lighter environmental footprints. Here’s what the numbers have to say.

Can a fire-ravaged forest of Joshua trees be restored?

VIDEO: In August 2020, the Dome Fire burned more than 40,000 acres of the iconic species’ range in the Mojave Desert, leaving a graveyard of blackened trees. A massive replanting effort now underway hopes to return life to the fragile ecosystem by boosting numbers of the climate-threatened plant.

Lyme and other tick-borne diseases are on the rise. But why?

The complex interplay of ticks, their habitats and hosts — along with changes in land use and climate — may be enabling the spread of the pathogens they carry

How to short-circuit short-term thinking

OPINION: Human behavior is fueling major social dilemmas — from climate change to the Covid pandemic to the spread of misinformation. But that means it’s also the solution, if only we can harness psychology for the common good.

Why there’s no such thing as pristine nature

A growing body of research shows that people have been shaping the planet for millennia — muddying the very idea of wilderness and prompting calls for a revolution in ecology and conservation

Substances that persistently luminesce are already used in some bike lanes, and in the future could be applied to sidewalks, streets and buildings — saving energy and reducing urban heat

Now is the time to prepare for the economic shocks of battling climate change

Shedding reliance on fossil fuels is key to making the leap from a carbon-intensive present to a greener future. Experts say that smart planning and transparent policymaking can ease the transition — and balance the worst financial risks.

How to handle climate anxiety

Worry over the planet’s future is taking a toll on emotional well-being, researchers say. Here’s how to cope so we don’t lose hope for our planet and for ourselves.

The case for ocean optimism

With the health of the ocean under threat, a rallying cry for marine conservation goes global. Here are some of the good-news stories.

Many mangrove restorations fail. Is there a better way?

These carbon-hoarding, coastline-protecting forests are sponges for greenhouse gases. Doing plantings right and involving local communities are key to saving them.

Let’s keep meetings virtual after Covid

OPINION: We don’t want to go back to living on planes and out of suitcases. Virtual meetings are cheaper, more accessible and better for the planet.
